Abstract

The invention relates to an anti-corrosive paint, which is prepared from the following raw materials by weight part: 25-30 of polyester resin, 10-13 of amino resin, 5-7 of epoxy resin, 15-18 of cellulose acetate butyrate, 0.1-0.2 of polyester modified polysiloxane, 5-8 of glycol diglycidyl ether, 6-8 of ethyl acetate, 1-2 of beeswax, 5-8 of isobutanol, 0.2-0.3 of sodium benzoate, 3-5 of fumed silica, 9-12 of talcum powder, 2-4 of a thermoplastic polyurethane elastomer, 6-13 of a pigment, and 4-6 of an adhesion assistant. The paint provided by the invention has good water resistance, chemical resistance, atmospheric stability and cold resistance. By using the thermoplastic polyurethane elastomer, the paint is not easy to be brittle and cracked. By using the fumed silica, the paint can have good gas barrier property, and delays the article surface corrosion. At the same time, the paint has strong adhesion, and good alkali resistance and salt fog resistance.

Description

A kind of non-corrosibility coating and preparation method thereof

Technical field

The invention belongs to paint field, relate in particular to a kind of non-corrosibility coating and preparation method thereof.

Background technology

The use field of coating is a lot of now, owing to being often exposed among atmosphere, be subject to the erosion of oxygen, moisture etc., easily cause the phenomenons such as corrosion of metal, foxy, cement weathering, raising along with people's living standard, requirement to coating each side all increases, especially more and more higher to the requirement of the aspects such as performance such as the hardness of coating, wear resistance, fullness ratio, shock-resistance, ageing resistance, anticorrosion, waterproof, grease proofing, chemicals-resistant, fast light, heatproof, therefore need the more progressive coating of research to meet people's needs.

Summary of the invention

The object of the present invention is to provide a kind of non-corrosibility coating and preparation method thereof, this coating has good water tolerance, chemical resistance, resistance to air stability, winter hardiness, is difficult for embrittlement dry and cracked, and gas barrier properties is good, strong adhesion, alkali resistance and salt fog resistance are good.

Technical scheme of the present invention is as follows:

A non-corrosibility coating, is characterized in that being made by the raw material of following weight part: vibrin 25-30, aminoresin 10-13, epoxy resin 5-7, cellulose acetate butyrate 15-18, polyester-modified polysiloxanes 0.1-0.2, ethylene glycol diglycidylether 5-8, vinyl acetic monomer 6-8, beeswax 1-2, isopropylcarbinol 5-8, Sodium Benzoate 0.2-0.3, aerosil 3-5, talcum powder 9-12, Polyurethane Thermoplastic Elastomer 2-4, pigment 6-13, adhere to auxiliary agent 4-6;

The described auxiliary agent that adheres to is made by the raw material of following weight part: thiosinamine 0.2-0.3, Silane coupling agent KH550 0.4-0.6, butyl acrylate 3-5,1,6 hexanediol diacrylate 4-7, urethane resin 6-8, chlorinated polypropylene 7-9, Tenox PG 2-3, tripoly phosphate sodium STPP 2-3, dicumyl peroxide 0.1-0.2, Isooctyl acrylate monomer 5-7, ethyl acetate 10-15, propyl carbinol 10-15, oleum lini 1-2, wet nurse fruit oily 1-2, nano titanium oxide 0.2-0.3; Making method is: ethyl acetate, propyl carbinol, oleum lini, wet nurse fruit oil are mixed, under 3000-4000 rev/min, add urethane resin, chlorinated polypropylene, after dissolving, add again butyl acrylate, 1,6-hexanediyl ester, stir 20-30 minute, add other remaining components, be heated to 80-90 ℃, stirring reaction 30-50 minute, obtains.

The preparation method of described non-corrosibility coating, is characterized in that comprising the following steps:

(1) prepare A component: ethylene glycol diglycidylether, vinyl acetic monomer are mixed, under 4000-6000 rev/min, add epoxy resin, vibrin, stir 30-40 minute, then add Polyurethane Thermoplastic Elastomer, beeswax, aerosil, stir 1-2 hour, make A component;
